German premium carmaker BMW said unit sales rose 7.6 percent in July, driven by growth in demand from the United States and China.

July sales of its BMW, Mini and Rolls-Royce brands rose to 129,094 vehicles it said on Monday.

We have just reported the most successful July sales ever and we are well on our way to achieving our recently announced target of over 1.6 million vehicles in 2011, the best ever sales result for the BMW Group, BMW's head of sales Ian Robertson said in a statement.

In the U.S., the company delivered 21,409 vehicles in July, 11.7 percent more than a year earlier. Growth in China was 36.1 percent with 18,858 cars sold.
